RADIATOR.

Application tiled August 4. 1917.

VTo @ZZ @07mm t may concer/n Be it known that l, l,VILLTAM SPARKS, a citizen of the United States el? America, and resident ot Jackson, in the county ot Jackson, in the State oit Michigan, have invented new and useful Improvements in Radiators, of Which the following, taken in connection With the accompanying drawings, is a full, clear, and exact description.

rlhis invention relates to certain impro'vements in radiators 'for liquid-cooled internal combustion engines commonly employed as the motive power tor automobiles, aeroplanes and analogous vehicles, in which the radiator is exposed to more or less liability to injury, as for example in War machines Where the radiators are liable to be punctured by bullets, fragments ot shrapne-l and other external object-s which, under the present construction, Would render the entire radiator useless.

The primary object of my present invention is to divide radiators of this type into a series ot separate or independent circulatory units or sections, each having a separate valved inlet and valved exit so that in case any one or more of said sections or units may become impaired, it may be readily cut out of the circulatory system as a Whole Without affecting the tree circula.- tion of the cooling agent through the remaining sections, thereby 3ermitt-ing the continued operation ot the engine Without material delay and still maintaining a suliicient circulation of the cooling agent to prevent overheating' ot the engine Another object is to provide simple means for assembling and retaining the entire series of radiator units or sections in lined relation, and at the same time to allow tree expansion or contraction of either unit without overstraining or loosening the connec@ tions between them.

@ther objects and uses relating to specific parts of the circulatory system will be brought out in the 'following description.

In the drawings- Figure l is a perspective view of a radiator embodying` the features of my invention.

series of similar interchangeable cellular units or sections Il of hollow, verticallyelongated formation and arranged side by side an upright position sol as to lie in substantially the same vertical plane in close juxtaposition, the entire series being bound together or embraced by a metal band -2- extending across the bottom and top of the entire series and along the outer upright faces of the end sections and provided with loyver and upper inturned llanges 3 lying against the front faces of the adjacent portions oi the sections to additionally support the same.

Each radiator section or unit is rigidly secured to the external frame or band *1;- by a separate set ot clamping screws -4` which are passed through apertures in the lower and upper sides of said frame and engaged in threaded sockets 5- in the adjacent portions of the radiator section, as shown more clearly in F ig. 2, each section being also provided with an inlet -6- and an exit -7- located, respectively, in the upper and lower portions ot the rear side or' the radiator', the inlets being` arranged near the top and the exit-s near the betteln.

rlhe inlets oit the several sections are connected by branch pipes *8- to a dissributing pipe or header 9* which is connected to the engine, not shown, by the usual uptlovv pipe, as -lO-, the header being also provided with a separate inlet 411- into which the cooling agent may be admitted in iilling the circulatory system, said inlet ll being normally closed by a screw cap -l2-- The exits -7- ot the several units are connected by branch pipes -13 to a separate distributing pipe or header -llsimilar to the header -9-, said header being connected by a return flow pipe -l5 to the engine, not shown.

Each of the branch inlet and exit pipes -tl and --13` is provided with a separate valve 1(5* for controlling the noiv oit the cooling agent to and from the corresponding radiator unit orsection, thus aei'iiiittiiig' any one or the sections which may become impaired tov be cut out from the rest ot the circulatory system and permitting the :tree tloiv of the cooling Vagent through the remaining sections.

lt is also evident that in case any one of the radiator sections becomes impaired,

uid connected to the inlet` el each e; said units and Valves for disconnecting any one 15 -o said unie from seid source oi duid, e

dieeneige for Huid connected to the outlet from eeen of seid units, wives for disconeetieg any one of said units from the seid diSChei'ge for fluid, e bend extending wound the assembled radiate? unis, and Ineens for See-fing each unit to the band.

En witness Wheiee have hereunto set my hand this 26th day ei"- July, 1917.
